Abstract
Chemically bonded ceramics and manufacturing processes are described. In one aspect, a manufacturing process of a chemically bonded ceramic is carried out by: (1) combining an acidic liquid and Fly ash to form a mixture; and (2) curing the mixture to form the chemically bonded ceramic. The Fly ash corresponds to at least a majority by weight of solids combined with the acidic liquid to form the mixture.
Claims19
A manufacturing process of a chemically bonded ceramic, comprising:
- combining an acidic liquid and Fly ash to form a mixture, wherein the Fly ash corresponds to at least a majority by weight of solids combined with the acidic liquid to form the mixture;
- and
- curing the mixture to form the chemically bonded ceramic.
A manufacturing process of a chemically bonded ceramic, comprising:
- forming an aqueous mixture including
- an acid and water in a combined amount corresponding to 20% to 67% by weight of the aqueous mixture, and
- Fly ash in an amount corresponding to at least 90% of a remaining weight of the aqueous mixture;
- and
- reacting the acid and the Fly ash in the aqueous mixture to form the chemically bonded ceramic.
